***WARNING***13APR08
Anyone using a Yamaha or Onkyo/Integra receiver or pre/pro should use extreme caution when bitstreaming DTS MA.

Users are reporting a loud "POP" that is described as a loud firework or gunshot when using one of the above listed receivers AND bitstreaming DTS MA. This can damage your equipment!!!
The theory is certain receivers have a faulty DTS decoder chip and when coupled with certain DTS MA tracks, will cause this issue.

Ronny Katz, the Sr. Manager of Professional Audio at DTS, has already responded to this thread (see post #599) and has stated the issue is not in the DTS track or stream, and to seek assistance from your specific AVR manufacturer. Mr. Katz will not comment any further on the issue.

It is unknown at this time if all or just some models are affected.
Certain members have been in contact with Yamaha and Onkyo, though nothing official yet, it does look promising.
It is unknown at this time if the receivers can be fixed via a firmware or may need a more involved matter like shipping your unit in for a hardware change.

"kinglerxt" has received a reply from Onkyo including a firmware fix for his particular model (see post #1788). Contact your Manufacturer or visit your official owners thread for more details.

In the mean time, I highly recommend anyone using any of these receivers to NOT listen to any bitstreamed DTS MA material.

Be aware that just because you played any of these titles, does not mean that you don't have a problem as it appears not all titles affect every receiver.
"The Fly" seems to be the definitive test that no one with stated equipment can pass.
**see link below for a video clip of the "POP"**Test at your own risk!!!

A big thanks to all forum members that discovered, reported, tested, theorized and most likely solved this issue!!!

*all above info is strictly speculation until an official announcement is made*

I've run across several posts now saying they have had issues with dts masters when bitstreamed to their receivers. Apparently it causes an extremely loud popping sound that can damage your speakers. (reminds me of when you would send bitstream dts to an incompatible receiver)

-The Fly
-Fantastic Four
-The Golden Compass
-Chronos

It is unknown if this is a disc, player or receiver problem but it only happens when Masters is bitstreamed to your receiver.

Please test at your own risk!!!
Even low volumes can damage your system!!!

If you have watched any of these movies AND are bitstreaming DTS masters to a 1.3 receiver please post your results and what player and receiver you are using.
Also, if you run across any other titles please post.

Chronos (near the end of the movie arouind 38:50 to 38:55 (38:52 exactly I think) where the camera is looking up at the cathedral ceiling with the lights shining thru)-kinglerxt

IMHO this is a HDMI cable issue, just a good guess, no proof, but this is the exact thing that would happen with high datarates dropping out because of a cheaper HDMI cable, those that are having this problem should order a silver blue jeans 24awg HDMI cable

I have tested various HDMI cables sending high bitrate audio etc., the cheaper ones dropped out randomly once every movie or two, causing pops and cracks, the higher end ones didn't, I haven't had such a problem in months and months since doing the testing which was a day or two after high bitrate audio capability hit

try it out

on a additonal note, the Samsung 1400 does this on it's own, dropping out for a split second and causing the cracks and pops

Anybody else see a common denominator? It looks like it could be the BD30. Anyone else experience this and was not using a BD30?
It should also be noted that not all BD30 users have experienced this problem.

The Fly (At the beginning of the movie when Jeff Goldblum goes to the magazines office, the main editor greets him and then walks out of his office door leaving Jeff Goldblum and Gina Davis in the office. Right when the door closes the audio goes ballastic.)-jsmiddleton4

Fantastic Four (Its the first scene where Reed and Victor are negotiating in his office. Right around the time they shake hands on the 75/25 deal.)-strange_brew

Wait the minute...so the OP's only claim is that it causes popping and no actual proof that it causes speaker damage? What the hell!

I can see that sustained, loud popping noises can cause speaker damage but this can occur with any signal, whether it is DTS-HD MA, or Dolby TrueHD or linear PCM. So the statement that DTS-HD MA causes speaker damage is a bit dubious.

Somewhat OT. This may be an Onkyo issue because I get a single pop that is so loud that the Onkyo goes into fault mode when watching On Demand with my Directv PVR. My heart goes into fault mode as well!

This is why when I originally posted this problem on Chronos in another thread I asked if it was a possible sub/setup issue
Mynew SVS PB10NSD sub wil be here soon because my old Infinity sub died a while back so Im technially only at 5.0 right now with no sub
So I was wondering if it was because I had no sub that it may have cause my mains to extend too far during that scene
Will have to retest on a VERY low volume when my sub arrives but if anyone else has Chronos, please test it to verify

Are you guys sure that you have proper speakers and proper powered subs that can handle lossless audio?
